The Centers for Disease Control and Prevention recommends that you stay home for at least 24 hours after your fever is gone, except to get medical care or other necessities. Your fever should be gone for at least 24 hours without the use of a fever-reducing medicine, such as Tylenol. You should stay home from work, school, travel, shopping, social events, and public gatherings.

Check with your child's daycare or school before sending your child back. Many have rules and it’s generally at least a full day after they don't have any fever without medication.

How long is a person with the flu contagious?

In general, about a week. People with the flu may be able to infect others from 1 day before getting sick to 5 to 7 days after. However, children and people with weakened immune systems can infect others for longer periods of time, especially if they still have symptoms.

What should you do while while sick:

Stay away from others as much as possible to keep from infecting them. If you must leave home, for example to get medical care, wear a face mask if you have one, or cover coughs and sneezes with a tissue. Wash your hands often to keep from spreading flu to others.

To do so, they compared the health benefits of the four most popular alternative milks, including soy, almond, coconut and rice. They examined the number of calories and amount of protein, fat and carbohydrates found in each. They also looked into the vitamins and minerals the substitutes contained.

While they said cow’s milk still has the most nutritional value, with 8 grams of protein, 9 grams of fat and 11.5 grams of carbs, soy is the most comparable for overall balance. It’s “a clear winner,” they wrote in a statement. It has more protein than all the other milk options analyzed, with 7 to 12 grams and 95 calories a glass. Scientists also credited soy milk for its phytonutrients, which have been linked to reducing cancer risk.

Almond milk is low in protein and carbohydrates, but it has fewer calories, with 36 per serving. It also is rich in monounsaturated fatty acids, which can help with weight loss and management. Previous studies have also shown that it can reduce cholesterol.

As for coconut milk, it’s low-calorie, too, but has no protein. Plus, the calories are mostly from saturated fats. And rice milk also has few nutrients. In fact, the researchers said “consumption of rice milk as an alternative to cow’s milk without proper care can result in malnutrition, especially in the case of infants.”

Dairy is one of the most common allergens among infants and children, the study explained, so many parents steer away from cow’s milk. Furthermore, lactose intolerance affects up to 75 percent of all adults, and those with the condition look to other alternatives.

Although the researchers believe their findings are strong, they said want to continue their investigations “to understand the effects of various conventional and novel processing methods on the nutritional profile, flavor and texture of these alternative milks.”

As the virus spreads in the lungs and respiratory system, the body unleashes a counterattack, in which T-cells destroy the tissues that harbor the invading virus.

“In most healthy adults this process works, and they recover within days or weeks,” the magazine reports. “But sometimes the immune system’s reaction is too strong, destroying so much tissue in the lungs that they can no longer deliver enough oxygen to the blood, resulting in hypoxia and death.”

Sometimes the lungs, weakened by the flu, become prey to another infection, often streptococcus, and the body is felled by bacterial overload, as happened to a New Hampshire mother of four earlier this month.

Doctors have long known that contracting influenza can be dangerous for the elderly, for infants and for those already in a weakened state. But flu can kill others as well, depending on the virulence of the particular strain that spreads during flu season.

When you're trying to lose weight, you may not give much thought to what you drink, but those calories definitely add up. These "liquid calories" can sabotage your weight-loss efforts, and you may not feel as full as if you'd eaten the same number of calories. Many drinks also provide little to no nutrients and are often loaded with sugar, which can further hamper your weight loss.

These drinks – and their calories – may add up to more than you realize, even on a single day. The Centers for Disease Control and Prevention offered a sample list of the drinks you may choose during a day in order to total the calories. They started with a morning coffee shop run with a 16-ounce café latte made with whole milk at 265 calories. A non-diet soda with lunch had 227 calories, and an afternoon sweetened lemon iced tea from the vending machine was 180 calories. A glass of non-diet ginger ale with dinner added 124 calories for a daily total of a whopping 796 calories!

Although at-home add-ins like creamer and sugar raise the calorie count, a specialty coffee can make it soar. A grande (16-ounce) size of white chocolate mocha espresso at Starbucks has 360 calories. If you choose a venti (20 ounces), you'll be drinking 460 calories.

Serving size is important, she pointed out. For example, a 20-ounce Angel Food smoothie from Smoothie King contains 340 calories. If you order the 40-ounce mixture of strawberries, bananas, nonfat milk, vanilla and other natural flavors and turbinado sugar, you'll be getting a whopping 690 calories. You can save some calories by omitting the sugar, saving 90 calories on a 20-ounce Angel Food smoothie, but it's still fairly high in calories.

It seems like there are new health trends popping up all the time – some super food promising to make you live forever or some natural remedy guaranteed to make you look younger.

We may roll our eyes with skepticism, suspecting that the claims are usually too good to be true. But there are actually a lot of normal things we readily do for our health, even though there is no real scientific evidence they help at all.

Some things we simply accept as healthy choices are even potentially detrimental to our well-being. Here's a look at five such "healthy habits" that aren't really as healthy as you think.

Although about 5 percent of Americans may suffer from excessive earwax, the vast majority don't need to be concerned. Ear wax actually benefits us by transferring dead skin cells out of our ears. It's also antifungal and antibacterial, meaning it works to keep our ears healthy.

Doctors also warn that Q-tips simply push the wax deeper into our ears.

"The diameter of the Q-tip is greater than half the diameter of the ear canal," Dr. Mark Vaughan told INSIDER in 2017. "So any way you stick that in there, there's a portion of the wax that you can't get around. All you can do is push it in."

2. Flossing

Proper teeth care is hammered into us from an early age. Ideally, we should brush and floss three times per day, about 30 minutes after every meal. But that's only half true.

While brushing is definitely important, flossing actually isn't.

That's right, even though dentists have been recommending flossing for decades, there's minimal scientific evidence that it's actually beneficial. An investigative report by an AP journalist published in 2016 revealed the lack of science behind the recommendations.

The report cited a 2015 scientific review that said: "The majority of available studies fail to demonstrate that flossing is generally effective in plaque removal." Another cited study said evidence of flossing's benefits is "weak" and "inconsistent."

3. Using hand sanitizer

If you're one who constantly carries hand sanitizer or keeps a bottle on your desk, you may want to reconsider. It's not that hand sanitizer is necessarily bad to use, it's just that soap and water is so much better.

"Unless there's a blockage in one of these organs that do it day and night, there's absolutely no need to help the body get rid of toxins," Dr. Ranit Mishori of the Georgetown University School of Medicine told NPR in 2012.

Three studies published in 2013 found no evidence that such supplements could reduce the risk of chronic conditions such as cancer and heart disease among well-nourished individuals. Essentially, if you're eating fine, you don't need to take the daily tablet.

When the studies were published, a group of doctors wrote an editorial specifically saying that there's "no substantial health benefit" to taking multi-vitamins. In fact, they could even cause harm to your health.

"Supplementing the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful," the doctors warned.

The initial focus of the new company will be on technology that will provide their employees with high-quality, reasonably priced health care.

“The ballooning costs of health care act as a hungry tapeworm on the American economy. Our group does not come to this problem with answers. But we also do not accept it as inevitable. Rather, we share the belief that putting our collective resources behind the country’s best talent can, in time, check the rise in health costs while concurrently enhancing patient satisfaction and outcomes,” said Berkshire Hathaway Chairman and CEO Warren Buffett.

“The health care system is complex, and we enter into this challenge open-eyed about the degree of difficulty,” said Jeff Bezos, Amazon founder and CEO. “Hard as it might be, reducing health care’s burden on the economy while improving outcomes for employees and their families would be worth the effort. Success is going to require talented experts, a beginner’s mind, and a long-term orientation.”

The chain said the recall was out of "an abundance of caution" after samples of one product from a single production day showed positive for listeria monocytogenes bacteria. Exposure to the bacteria can cause fever and diarrhea, with particularly dangerous symptoms for pregnant women and unborn children.

To do so, they used X-ray fluorescence technology to examine 200 plastic toys, such as cars, trains, figures and puzzles, which were found in nurseries, thrift shops and homes across England. They were inspecting the items for nine hazardous elements, including antimony, barium, bromine, cadmium, chromium, lead and selenium.

After analyzing the results, they found that 20 toys had traces of all nine elements, which can be chronically toxic if children are exposed to them at low levels. If the kids put the products in their mouths, they can be introduced to the toxins faster.

"Consumers should be made more aware of the potential risks associated with small, mouthable and brightly coloured old plastic toys or components,” coauthor Andrew Turner told BBC. "Without that, the attractive cost, convenience and recyclability of previously used toys has the potential to create a legacy of chemical contamination for younger children."

Furthermore, a few of the toys didn’t comply with standards set by the European Council's Toy Safety Directive. In fact, red, yellow or black plastics were the worst, because they had too much too much bromine, cadmium or lead.

Apple is taking a new step to bring your life into one location. The tech giant has updated its Health app so users can upload their health records onto their phones and have them accessible on both phones and Apple Watches.

Apple worked with hospitals to use Fast Healthcare Interoperability Resources, or FHIR, to transfer electronic records to the devices and to keep them secure.

Apple Health will combine information and update it with the latest medical records. In the past, patients had to download their records and manually upload them into the program, The Washington Post reported.
